Strange Powermac G4 Startup Problem

strange for me at least..

i work at a university and have encountered a weird startup issue that i am experiencing with three different powermac machines. hopefully, someone here can provide some insight..

well, on all three machines there seems to be an issue with the mac powering up to the OS. first of all, they appear to startup normally (including start sound, and apple load up screen with the progress circle). but, they all load to a blank white screen now.

now i have already tried resetting the pram, nvram, and the pmu. unfortunately, this leads to equally negative results. if the white screen does not appear, another alarming notice screen appears in it''s place. this other screen explains the computer cannot startup to the OS and requires me to manually reset the computer/s.

so, i then tried to reinstall the operating system by starting up to the CDs provided. however, this not work since the ctrl-c boot does not work at all on all machines.

the only thing i can imagine happening is that there is a hard drive failure on these macs. but, i want to make sure i have exhausted every last option before calling apple and paying for their support.

please, if anyone can provide any advice or point out something i may be overlooking, let me know. i thank all of you in advance for any future assistance on this matter.

the only thing I can contribute is that it isn't CTRL-C it is just C. Just hold down the C and it boots from the CD-ROM.

Hope that helps.... I've been through it

What is the ctrl-C boot. Isn't it, you boot the system and hold down the C key. Be dure that a bootable CDROM is in the CDROM drive.

Three machine experiencing trhe same problem is scary.

You do have a good cdrom disk? I have stated this else where, because I have found that if you have a bad cdrom disk it can you to have a bad day.

What version of the OS were you at? I have had a problem similar to this. My G3 was running OS 10.1.5. I had tried everything I could with the help of gatorparrot. I ended up reloading the system.

i believe my discs are good. but honestly, i have only tried one set of the 4 restore discs, assuming these discs were fine. unfortunately, the retail osx discs cannot be used on the powermac g4s. i guess i can try an alternate set of 4 and see if that works.

btw - all machines in the lab are running both osx and os9. i believe the osx is version 10.2.6... (i am not work at the moment) thanks again for all of yr responses and help! i appreciate it greatly!
